Method and apparatus for dynamic analysis of images of a mobile object. An electronic signal corresponding to the images, for example, from a video camera, is input into a digitizer which identifies the coordinates of the periphery of the mobile object in each of the images. A digital processor processes the contour information and a computer controlled by a software program having image processing and graphics capabilities calculates a plurality of parameters representative of the shape and motion of the object. The output from the computer may be displayed in graphical representations tabular form, in the formation animations on a monitor, or in hard copy printouts of the tables, animations and other graphical representations.
